Note that L{header} and L{blocks} are not automatically kept in sync with the rest of the nif data, but they are resynchronized when calling L{write}.

Variables:	version – The nif version. user_version – The nif user version. user_version2 – The nif user version 2. roots – List of root blocks. header – The nif header. blocks – List of blocks. modification – Neo Steam (“neosteam”) or Ndoors (“ndoors”) or Joymaster Interactive Howling Sword (“jmihs1”) or Laxe Lore (“laxelore”) style nif?

inspect(stream)¶

Quickly checks whether the stream appears to contain nif data, and read the nif header. Resets stream to original position.

Call this function if you only need to inspect the header of the nif.

Parameters:	stream (`file`) – The file to inspect.

inspect_version_only(stream)¶

This function checks the version only, and is faster than the usual inspect function (which reads the full header). Sets the L{version} and L{user_version} instance variables if the stream contains a valid nif file.

Call this function if you simply wish to check that a file is a nif file without having to parse even the header.

Raises ValueError:
	If the stream does not contain a nif file.
Parameters:	stream (`file`) – The stream from which to read.

read(stream)¶

Read a nif file. Does not reset stream position.

Parameters:	stream (`file`) – The stream from which to read.

write(stream)¶

Write a nif file. The L{header} and the L{blocks} are recalculated from the tree at L{roots} (e.g. list of block types, number of blocks, list of block types, list of strings, list of block sizes etc.).

Parameters:	stream (file) – The stream to which to write.

Default for uvprecision should really be high because for very large models the uv coordinates can be very close together.

For vertexprecision, 3 seems usually enough (maybe we’ll have to increase this at some point).

Parameters:	vertexprecision (float) – Precision to be used for vertices. normalprecision (float) – Precision to be used for normals. uvprecision (float) – Precision to be used for uvs. vcolprecision (float) – Precision to be used for vertex colors.

add_child(child, front=False)¶

Add block to child list.

Parameters:	child (L{NifFormat.NiAVObject}) – The child to add. front (`bool`) – Whether to add to the front or to the end of the list (default is at end).

add_effect(effect)¶

Parameters:	effect (L{NifFormat.NiDynamicEffect}) – The effect to add.

get_children()¶

Return a list of the children of the block.

Returns:	The list of children.
Return type:	`list` of L{NifFormat.NiAVObject}

Returns:	The list of effects.

get_skinned_geometries()¶: This function yields all skinned geometries which have self as skeleton root.

merge_external_skeleton_root(skelroot)¶: Attach skinned geometry to self (which will be the new skeleton root of the nif at the given skeleton root). Use this function if you move a skinned geometry from one nif into a new nif file. The bone links will be updated to point to the tree at self, instead of to the external tree.

merge_skeleton_roots()¶

This function will look for other geometries whose skeleton root is a (possibly indirect) child of this node. It will then reparent those geometries to this node. For example, it will unify the skeleton roots in Morrowind’s cliffracer.nif file, or of the (official) body skins. This makes it much easier to import skeletons in for instance Blender: there will be only one skeleton root for each bone, over all geometries.

The merge fails for those geometries whose global skin data transform does not match the inverse geometry transform relative to the skeleton root (the maths does not work out in this case!)

Returns list of all new blocks that have been reparented (and added to the skeleton root children list), and a list of blocks for which the merge failed.

remove_child(child)¶

Remove a block from the child list.

Parameters:	child (L{NifFormat.NiAVObject}) – The child to remove.

remove_effect(effect)¶

Remove a block from the effect list.

Parameters:	effect (L{NifFormat.NiDynamicEffect}) – The effect to remove.

send_bones_to_bind_position()¶

This function will send all bones of geometries of this skeleton root to their bind position. For best results, call L{send_geometries_to_bind_position} first.

Returns:	A number quantifying the remaining difference between bind positions.
Return type:	`float`

send_detached_geometries_to_node_position()¶

Some nifs (in particular in Morrowind) have geometries that are skinned but that do not share bones. In such cases, send_geometries_to_bind_position cannot reposition them. This function will send such geometries to the position of their root node.

Examples of such nifs are the official Morrowind skins (after merging skeleton roots).

Returns list of detached geometries that have been moved.

send_geometries_to_bind_position()¶

Call this on the skeleton root of geometries. This function will transform the geometries, such that all skin data transforms coincide, or at least coincide partially.

Returns:	A number quantifying the remaining difference between bind positions.
Return type:	`float`

set_children(childlist)¶

Set the list of children from the given list (destroys existing list).

Parameters:	childlist (`list` of L{NifFormat.NiAVObject}) – The list of child blocks to set.

set_effects(effectlist)¶

Set the list of effects from the given list (destroys existing list).

Parameters:	effectlist (`list` of L{NifFormat.NiDynamicEffect}) – The list of effect blocks to set.
